The Signature T isn't the same as the Traditional. The Les Paul Traditional is actually the old spec Standard. Pre- 2008 spec, IIRC. By, "traditional weight-relieved body" they mean the 7-hole Swiss cheese which started around 1983. I guess you could call 30 years a tradition. But the Les Paul's everyone considers the pinnacle are the 1958, 1959 and 1960 guitars. These are solid body guitars with no wood removed for the sake of making them lighter. All of the Reissue/Historic's (ie., Gibson Custom Shop) are still built this way. I really like my 2012 spec. Standard. They are weight-relieved but not chambered. It's a different process then the older 7-hole though. Sounds nice and full. I don't really like the chambered LP's. They removed too much wood and they sound thin as you said.
